By Expert Author: sally yang

We know that the lens is divided into telephoto lens, zoom lens, wide-angle lens . Learn about the classification of the lens , choose your favorite body after , before you start buying lenses, please think about these questions , of course, rich friends can ignore the following questions:

1.What the largest number of its own budget? Do not look at a few articles , look at a few stickers on random drug to improve their budget , the best friend just started SLR practical way is to start , or buy a cow is not able to play it back to power , and the backlog funds .
2.What shot up to their daily ? I write with reference to the front , you would like to shoot portraits such election 35-135 focal length lens. Like to shoot landscapes, tourist would choose a 17-35 wide-angle focal lengths . Like to shoot flowers, pictures of birds should consider a 200mm focal length lens.
3.what the imaging requirements of high? This is a big problem , in the end what is called a good image ? There are many standards related bickering since this thing has been shot in the fight . Simply put image clarity, color purity, the sharp focus , soft -focus , better performance level of detail . I think this would analyze their own photos from head to like, for example, just patting fun, general How to choose the best camera lens will be enough , if it is to work in photography , advertising what to shoot , it's still necessary to choose a professional lens.
4.six months will upgrade the short term ---SLR into a pit , no eternal life. Nikon reason was called " mud " is justified , I really have not met the body do not want to buy a SLR interchangeable lenses , lens upgrades person . So when buying lenses may wish to consider that he is not in need of an upgrade, consider the problem of preservation of the lens .

SLR lens is characterized by relatively preserved , at least more than the card cameras, mobile phones to hedge more. Generally Condition good , licensed , and warranty lens, used in about 90% of the price of the original price . Figuratively , for example, now spend $1200 to buy a Nikon 85mm F1.4D this portrait lens brand and warranty , the use of 10 months , the lens without any problems , Condition good protection , packaging invoice is complete, it can be out probably around $1000 . Loss of $ 1K When is this year's depreciation as well. Think about it is more cost effective , after 10 months of use it but a brand lens. Of course, some people say that this $1200 take stock 10 months may have earned a 1K , but after all, can not say that there is the risk of it as long as Condition good lens , the lens is almost secondary market brand popular .

There are many grades of Nikon lenses , as long as a few hundred dollars of low-end , high-end to more than ten thousand . Newcomers often do not understand, I talk about how simple judgments.
Generally there are a few basic lens truth:

1.the same focal length fixed focus imaging better than zoom. This is because the image quality zoom to consider several focal lengths , while the fixed focus is very simple to do only one focal length on OK.
2.the larger the aperture the more expensive, more expensive large aperture constant . The larger the aperture , the greater the technical difficulty , the cost is high, so a large aperture lens, commonly known as the "big eyes ." That watery eyes , but very attractive ah ! Like the "big eyes " means money bag , hey , the taste of which only themselves to experience it.
3.the heavier the better the lens , the lens of the manufacturers guide price is certainly good .
Each camera has its own gold imaging aperture imaging in general F5.6/8/11 will be better , different optimal imaging lens aperture different models , we need to understand their imaging lens as much good with it focal length and aperture to take pictures .
4.all brands of lenses , as long as the zoom lens, and a constant aperture would certainly not bad , constant aperture bigger the better. Nikon civilian biggest constant aperture zoom lens is 2.8 .
